and transmitting character of such links. At'

tempts heretofore made to overcome this disadvantage have resulted in the adoption of various hangers of a resilient type or of a type in which two parts were separated by a single layer of felt. Neither of these types of hangers are completely satisfactory due to the fact, in the first instance, that there is a continuous metal to metal contact betweenadjacent elements in spite of the resiliency, and, in the second instance, to the fact that where only a single layer of felt is interposed between two pieces of metal there is no true resiliency and the .felt promptly wears through and leaves a metal to metal contact.

My invention `comprises an isolating hanger in which not only'are the parts of the hanger relatively'movable but in which, between adjacent metal parts, are arranged layers of a resilient and sound absorbing material. Y

An object of the invention is to provide a novelform of isolating hanger in which is broken a through metal to metal contact between thefloor and a ceiling suspended thereby. n Another object of my invention is to provide a novel hanger in which a resiliency is interposed between a supporting iioor and a ceiling supported thereby.

Yet another object of my invention is to provide a novel isolating hanger in which not only is the connection between la 'supporting yiioor and a supported ceiling made resilient but also the continuous metal connection between the floor and ceiling is broken by a non-metallic link.

Other objectsand advantages of my invention will'be apparent from vthe following specification, claims, and from the drawing, in which:

Fig. 1 is a side elevation, partially in section, on the line I-I of Fig. 2, showing one embodiment of my invention as employed in supporting a ceiling from a oor construction.. Y

Fig. 2 is an elevation, partially in section, on the line 2 2 of Fig. l, of the embodiment of my invention shown therein;

Fig. 3 isan enlarged vertical elevation taken on the line 3-3 of Fig. 2, showing in detail the Fig. 4 isan elevational view, `partially in Sei;` tion, of a modified form of my invention;

(Cl. 'l2-118) Fig. 5 is a.V horizontal sectional view taken on the line v5 5 of Fig. 4j and Fig. 6 is a detail view of yet another embodiment of my invention.

The isolating hangers rcomprising my inven-y 5 tion and illustrated in Figs, 3 to 5 inclusive each is for the same purpose and may be similarly at-` tached or connected toa ceiling,` and they, as well as the embodiment shown in Fig. 6, may' be similarly connected to a oor. Referring par- 10 n ticularly to Figs. 1 to 3 inclusive, a oor F 'of concrete or similar material when being formed about reinforcing R may be poured about a metallic strap Ill, preferablyhaving in its upper end a right angle bend II. hangers embodying my invention may be thereafter connected as hereinafter described, or the hanger may be attached to the strap prior to the pouring of the concrete. To the lower end ofthe hanger a' strap 23 `is connected which inY turn sup- 20TY ports light channels l413 which in turn support, by means of links 45, cross furring members 45 to which suitable panels 41 may be directlyconJ nected.` Referring now to the embodiment of my inven- 251 tion illustrated in Figs. 1 to 3, a hole I2 is made in the strap I0 adjacent its lower endthrough which may be passed a bolt I3 having on one end a nut I4. Each end of two composite exible strips I5-I5 is perforated to' allow passage 30' therethrough of the bolt I3, the strips being mountedupon the bolt on either side ofthe strap I0 and each spaced therefrom by washers I6 which vmay be ofA a suitable resilient and nonmetallic nature such as felt, brake lining, leather, or the like. The` resilient strips I5 comprise in` wardly facing portions I 5a of brake lining or other similar materialfof hightensile strength and nre-resisting characteristics, `and each of these strips maybe backed by a thin layer of metal I5b such as sheet brass. The lower ends -of the strips I5 are perforated vsimilarly to the upper ends and these are, connected by a bolt 20 and nut 2| and spaced therefrom by resilient and non-metallic washers 22 to ak vertical strap23 45 which extends downwardly Vbelow the endsofthe strips I5. As illustrated, the centersof the holes in opposite ends ofthe backing ISUare spaced slightly further apart thanY are the. holes in the inner portions I5b so that no tensile stress 50 is exerted on the metal strips. These are designed solely as a safety measureY for use only if f the straps should be burnt. Interposed between the innerA opposite` faces I5a of the strips I5 is an expansion spring 25 held in location by oppositely 55 To this strap' theV15 facing caps 26 which may be held in position by rivets 21 passing therethrough and through preferably only the inner portion Ia of the strips I5.

The embodiment of my invention shown in Figs. 4 and 5 may be attached to the floor and to the ceiling supporting structure similarly to that shown in Figs. 1 to 3. In this embodiment, however, the strap I is connected by a bolt 30, passing through an opening in the lower end of the strap, and nut 3|, to a U-shaped metallic member 32 lined with a non-conductive, nonmetallic material 33 such as brake lining, leather, or the like. Since in this embodiment of my invention ther metal supports the ceiling there is no requirement that the lining 33 necessarily be reproof, although, under present day building requirements such construction is preferred. This material extends the full length of the metal member 32 and acts as a washer between' the ends thereof and the strap lll, thus isolating the metal of the U-shaped member 32 from that strap. A member 35 and lining 35 both identical in construction with the members 32 and 33 passes through the latter at right angles thereto, and it'is connected at its lower end by bolt 36 to the lower strap 23. Between the bottoms indicated at 32a and 35a of the U-shaped members 32 and 35 is interposed an expansion spring 38 spaced from the linings thereof at opposite ends vby washers 39. going description and from a consideration of the drawing it will be obvious that the metal contact between the adjacent U-shaped elements is broken and that resiliency is imparted to the hanger by the spring 38.

In the embodiment of my invention illustrated in Fig. 6 the strap I0 is connected to a member essentially similar in shape to that illustrated at 32 in Fig. V4,Y namely: a U-shaped member 4!) within which,and preferably adhesively secured to the inner walls thereof, is a thick layer of felt 4| surrounding,A adjacent the lower end of the U, a U-shaped frame 42 adapted to carry a channel member 43 which acts as a ceiling carrier. The channel member 43, or preferably the inner portion of the U-shaped frame 42, is lined with a layer'of felt 44. In this embodiment of my invention it will appear that the metal to metal contact is broken not only by the felt lining 4| but also by the lining 44. 'I'hese two linings are maintained out of contact with each other and the wear of the channel members spread over a large portion of felt lining 4|, by the inner U- shaped member 42.
